SUBMITTED PHOTO Following in the footsteps of Galileo, Southport High School’s Advanced Placement physics students performed his incline plane experiment by measuring the acceleration of a cart rolling down an incline at different angles. After collecting and analyzing their data, the students compared their Galileo value of gravity with the accepted value of gravity. The students, who included (from left) Htayni P. Sui, Ethan Knox and Lian S. Sang, were successful in their trials.
